Is the Nikon Mirrorless “Q” camera ready to be unveiled?

Sounds like Nikon will present their mirrorless “Q” camera at Photokina (next week). I don’t know if they will release a real camera or just present the new system with sme prototype. Anyway, there is a long Nikon mirrorless patent history that leads us to believe the sensor will be smaller than APS-C. I guess on Monday we will know more!
